Class Phalcon\Cache\Backend\Memcache¶extends Phalcon\Cache\Backend implements Phalcon\Cache\BackendInterface Allows to cache output fragments, PHP data or raw data to a memcache backend This adapter uses the special memcached key “_PHCM” to store all the keys internally used by the adapter <?php
// Cache data for 2 days
$frontCache = new Phalcon\Cache\Frontend\Data(array(
"lifetime" => 172800
));
//Create the Cache setting memcached connection options
$cache = new Phalcon\Cache\Backend\File($frontCache, array(
'host' => 'localhost',
'port' => 11211,
'persistent' => false
));
//Cache arbitrary data
$cache->store('my-data', array(1, 2, 3, 4, 5));
//Get data
$data = $cache->get('my-data');
Methods¶public __construct (Phalcon\Cache\FrontendInterface $frontend, array $options) Phalcon\Cache\Backend\Memcache constructor protected _connect () Create internal connection to memcached public mixed get (int|string $keyName, long $lifetime) Returns a cached content public save (int|string $keyName, string $content, long $lifetime, boolean $stopBuffer) Stores cached content into the Memcached backend and stops the frontend public boolean delete (int|string $keyName) Deletes a value from the cache by its key public array queryKeys (string $prefix) Query the existing cached keys public boolean exists (string $keyName, long $lifetime) Checks if cache exists and it hasn’t expired public __destruct () Destructs the backend closing the memcached connection public mixed start (int|string $keyName) inherited from Phalcon\Cache\Backend Starts a cache. The $keyname allows to identify the created fragment public stop (boolean $stopBuffer) inherited from Phalcon\Cache\Backend Stops the frontend without store any cached content public mixed getFrontend () inherited from Phalcon\Cache\Backend Returns front-end instance adapter related to the back-end public array getOptions () inherited from Phalcon\Cache\Backend Returns the backend options public boolean isFresh () inherited from Phalcon\Cache\Backend Checks whether the last cache is fresh or cached public boolean isStarted () inherited from Phalcon\Cache\Backend Checks whether the cache has starting buffering or not public setLastKey (string $lastKey) inherited from Phalcon\Cache\Backend Sets the last key used in the cache public string getLastKey () inherited from Phalcon\Cache\Backend Gets the last key stored by the cache |
